Amphibians are soft-skinned organisms that live near watery habitats similar to the ones their ancestors left over 365 million years ago. View images and photographs of 12 fascinating amphibians, including frogs and toads, caecilians, and newts and salamanders.
The axolotl is a salamander native to central Mexico’s Lake Xochimilco. When axolotl larvae reach maturity, they do not undergo metamorphosis. Instead, they retain their gills and remain completely aquatic.
Painted Reed Frog
The painted reed frog is native to Africa’s eastern and southern regions, where it lives in temperate forests, savannas, and scrublands. Painted reed frogs are small to medium-sized frogs with curved snouts and toepads on all four toes. The painted reed frog’s toe pads allow it to cling to plant and grass stems. Painted reed frogs are brightly colored frogs with a variety of patterns and markings.
The California Newt
The California newt lives in California’s coastal regions as well as the Sierra Nevadas. This newt produces tetrodotoxin, a potent toxin that pufferfish and harlequin frogs also produce. There is no antidote known for tetrodotoxin.
Red-Eyed Tree Frog
The red-eyed tree frog is a member of the new world tree frogs, a diverse group of frogs. The red-eyed tree frog is an excellent climber. They have toepads that allow them to cling to a variety of surfaces, including the undersides of leaves and tree trunks. They are distinguished by their bright red eyes, which are thought to be an adaptation to their nocturnal habits.
The fire salamander is a black salamander with yellow spots or stripes that lives in the deciduous forests of southern and central Europe. Fire salamanders frequently seek refuge in the leaves on the forest floor or on the mossy trunks of trees. They keep a safe distance from streams or ponds, which they use for breeding and brooding. They are most active at night, but they can also be found during the day.
